### Class

# GIRepository TypeInfo

since: 2.80

#### Description [src]

    final class GIRepository.TypeInfo : GObject.TypeInstance
    {
      /* No available fields */
    }

`GITypeInfo` represents a type, including information about direction and transfer.

You can retrieve a type info from an argument (see `GIArgInfo`), a function’s return value (see `GIFunctionInfo`), a field (see `GIFieldInfo`), a property (see `GIPropertyInfo`), a constant (see `GIConstantInfo`) or for a union discriminator (see `GIUnionInfo`).

A type can either be a of a basic type which is a standard C primitive type or an interface type. For interface types you need to call `gi_type_info_get_interface()` to get a reference to the base info for that interface.
